"The death appears to be natural causes at this point pending toxicology results," said Coroner Ken Bacha. He added that there is "no apparent public health concern."

A Norwin spokesman said that the student died unexpectedly at home Sunday.

Principal Timothy Kotch wrote a letter to parents about the situation. He said the student was active in school and community events but is not being publicly identified, based on the parents' wishes.

"The parents of the student have requested the memory of their son be honored by performing a random act of kindness. Consider visiting the elderly, donating to a worthy cause, or helping a fellow student," Kotch wrote. "The performance of a random act of kindness is representative of the personal character and life led by this student."
